Currently we are using Ubnt Rocket 90deg sectors although I have considered these to really be more like 75 degrees due UBNT using -6dB as the rolloff point. We have seen a dramatic improvement with a Titanium sector and plan on replacing the other rockets with Titaniums and considering going to 60deg or maybe even 45 degree and using GPS sync to reuse channels. What if any have been your experiences with going to narrower sectors for a given area? I would expect to see ~3dB improvement in links just by reducing the antenna pattern, and ~3dB due to power density. Additional gains might be made from improved F/B rejection and improved shielding, possibly another ~3dB? This could mean anywhere from 6-9dB improveme nt on every link. What are your experiences with UBNT GPS? We would not use dynamic, but rather fixed downlink %. I know we will give up some B/W but better spectrum management might be worth the trade. The link improvements should push the radios into higher modulation further mitigating the loss by using GPS Thoughts? Comments? Jerry -- Sent from my Android device with K-9 Mail.
